Advanced heart disease was cited as a factor in Koehler's original autopsy, which ruled the death natural. The cause of death was changed to undetermined after Lansing police began investigating Pena and Harris in connection with Koehler's death.

"These two took advantage of an elderly disabled victim because he was an easy victim," said his daughter, Sara Koehler. Larry Koehler did not have full use of one arm due to polio.

"The way the Lansing Police Department was able to solve the case was because of some of the bragging that had been done about what happened," Assistant Ingham County Prosecutor Danielle Cusson said during Wednesday's sentencing.

Laurie Desilva, also Koehler's daughter, spoke about him as the "growly bear" to her kids.

"I remember his curly hair, his mustache and his little left arm from polio," she said. "He used to give me bear hugs and for a time he was grandpa growly bear to my girls."

Draganchuk addressed Harris before announcing his sentence: "You have no remorse whatsoever for your actions. No matter how you describe it, you caused this man’s death ... you truly took advantage of him."

Harris declined to comment.

In a tearful statement, Pena apologized to Koehler's daughters. "There are really no words," she said. "The loss of a parent is something you never get over. ... I'm sorry."
